Form theory - locking a field

[Clive Bruton]

I have a form in which, after filing, I would like one field to be
locked for editing, the forms.py looks like this:

**************

class ProfileForm(forms.ModelForm):
status = forms.ChoiceField(choices=Profile.status_choices,
widget=forms.RadioSelect)

class Meta:
model = Profile
fields = (
'status', 'phone', 'display_phone', 'display_address',
'display_email', 'display_loginoverride'
)
widgets = {
'phone': PhoneWidget
}

**************


While the user will be able to come back and change the other
information on the form, I want to be able to lock the "status"
field, so that it just shows the input they selected, not the radio
buttons and is no longer editable by the user.

Is there a way to do this in forms.py, or would I have to construct
the logic in a template (or perhaps some other way)?

Thanks

Ok, well that's a little help, because I can disable the input:

status = forms.ChoiceField(choices=Profile.status_choices,
widget=forms.RadioSelect(attrs={'disabled': True}))

And I can put a "useless" if statement around it to get different
outputs:

if 1 == 1 :
status = forms.ChoiceField(choices=Profile.status_choices,
widget=forms.RadioSelect(attrs={'disabled': True}))
else :
status = forms.ChoiceField(choices=Profile.status_choices,
widget=forms.RadioSelect(attrs={}))

But, I can't work out how to get a meaningful if comparison, like:

if Profile.status == 'personal' :
status = forms.ChoiceField(choices=Profile.status_choices,
widget=forms.RadioSelect(attrs={'disabled': True}))
else :
status = forms.ChoiceField(choices=Profile.status_choices,
widget=forms.RadioSelect(attrs={}))

Any string I put in 'personal' always returns false, so I can switch
the output with "==" or "!=", but I can't assess the output in
reference to what I expect to be in the database fields. Django
accepts "Profile.status" as a relevant property, so I am a bit lost
as to how to continue, or debug this. If I try "print(locals()) or
print(Profile.status) I get no output in the terminal.
